I would like to automatically run a script after grub-install (using Grub2) if it's possible?

Some context. The script will simply run grub-install /dev/sda1, grub-install /dev/sdb1, grub-install /dev/sdc1 as I want all three EFI boot partitions in sync.

grub-install is a shell script, just edit it –  warl0ck Oct 20 '12 at 0:04
    
@warl0ck: I think it will get removed when an update of grub-install occurs. Which might very well be just when I need it. –  Deleted Oct 22 '12 at 17:46

You can simply put grub-install along with these three commands in a file and add it somewhere in the PATH so that you can run it whenever you need to.

Alternatively alias grub-install in root's ~/.bashrc (depending on what shell root uses) to grub-install && grub-install /dev/sd{a,b,c}1

My main concern is when doing apt-get dist-upgrade, I want all three HDD's to get updated then. I don't think .bashrc is read when running commands through sudo. Creating a script and putting it somewhere on roots path also doesn't help, as it's not only when I run it I want to make sure all three HDD's are addressed. –  Deleted Oct 20 '12 at 19:50
